目的检测2型糖尿病患者血清中半胱氨酸蛋白酶抑制剂C(CysC)、脂蛋白(a)[LP(a)]、载脂蛋白A1 (ApoA1)、载脂蛋白B(ApoB)和超敏C反应蛋白(hs- CRP)水平,并探讨其临床意义.方法 96例2型糖尿病患者分为单纯糖尿病组50例、糖尿病肾病组46例,另选择50例健康体检者作为对照组,分别检测各组血清中的CysC、Lp(a)、ApoA1、ApoB以及hs-CRP水平.结果 2型糖尿病组与对照组比较,CysC[(0.95±0.16)mg/L对(0.46±0.17)mg/L,P＜0.01]、LP(a) [(214.8±182.3)mg/L对(113.1±76.2)mg/L,P＜0.01]、hs- CRP[(2.57±1.84)mg/L对(1.07±0.38)mg/L,P＜0.01]、ApoB[(1.12±0.18)g/L对(0.81±0.15)g/L,P＜0.01]水平均升高；而ApoA1水平降低[(1.02±0.17)g/L对(1.27±0.14)g/L,P＜0.01].糖尿病肾病组CysC(2.14±0.68)mg/L、Lp(a)(455.6±263.5)mg/L、hs- CRP(7.24±4.55)mg/L、ApoB(1.22±0.17)g/L,均高于单纯糖尿病组(均P＜0.01).2型糖尿病患者尿微量白蛋白与hs- CRP (r=0.478,P＜0.01)、CysC(r=0.55,P＜0.05)、Lp(a) (r=0.487,P＜0.05)、ApoB(r=0.505,P＜0.05)呈正相关,与ApoA1(r=-0.52,P＜0.05)呈负相关.结论 CysC、Lp(a)、hsCRP、载脂蛋白可作为诊断糖尿病早期肾损害的敏感指标,联合检测更具实用价值.

Objective To study the clinical significances of serum lipoprotein (LP),high sensitivity C- reactive protein (hs CRP),cystatin (Cys-C),apolipoprotein (Apo) in type 2 diabetic mellitus (T2DM) patients with early renal impairment.Methods Totally 96 patients were divided into two groups:50 cases in simple diabetic group (DM) aged 60-73 years,46 cases in diabetic nephropathy group (DN) aged 61-72 years,and 50 healthy persons as normal control group aged 61-68 years.Serum levels of LP(a),hs-CRP,Cys-C,ApoA1 and ApoB were detected.Results Serum levels of LP (a) [(214.8±182.3) mg/L vs.(113.1±76.2) mg/L],Cys-C[(0.95±0.16)mg/L vs.(0.46±0.17) mg/L],hs-CRP (2.57± 1.84) mg/L vs.(1.07±0.38)mg/L] and ApoB [(1.12±0.18) g/L vs.(0.81 ±0.15) g/L ]were higher in T2DM patients than in normal control group(all P＜0.01),while ApoA1 level was lower than in control[(1.02±0.17)g/L vs.(1.27±0.14)g/L,P＜ 0.01].The levels of LP (a) (455.6 ± 263.5 ) mg/L,Cys-C (2.14 ± 0.68 ) mg/L,hs-CRP (7.24±4.55)mg/L and ApoB(1.22±0.17)g/L in DN group were increased compared with DM group (all P＜0.01).Serum levels of ApoA1 were decreased in DN group compared with DM group [(0.88±0.17) g/L vs.(1.02±0.17) g/L,P＜0.01].The serum levels of LP (a) (r=0.487,P＜0.05),Cys-C(r=0.55,P＜0.05),hs-CRP(r=0.478,P＜0.01) and ApoB(r=0.505,P＜0.05) were positively correlated with urinary mAlb in T2DM patients,while ApoA1 was negtively related with mAIb(r=-0.52,P＜0.05).Conclusions The serum LP (a),Cys C,Apo and hsCRP could be sensitive markers of early renal impairment,and their combinatorial measurement offers more value in patients with T2DM.
